BACKGROUND

Gaming, or poker machines, have become a major source of amusement and diversion in such places as clubs, hotels and casinos in many parts of the world.

Traditionally, such machines were mechanical devices where a number of reels marked with a plurality of numbers or symbols could be made to spin randomly by the application of some mechanical input. If the subsequent patterns of numbers or symbols displayed on the reels, when these returned to a rest state, corresponded to predetermined patterns, the machine would provide a prize or payout. Generally such gaming machines have come to be regulated by government authorities as to their number and in the manner in which the machines must return a percentage of the monetary turnover to the players.

The introduction of electronics, computers and electronic graphical displays, has allowed a continual increase in the complexity and variations of gaming machines, games and displays while maintaining the basic concept of the traditional machine.

Machines and games that offer novel and stimulating variations on the basic game theme and environment are eagerly sought by the gaming industry and there is consequently intense competition between machine manufacturers to innovate.

Nevertheless the repetitive playing of even modern gaming machines can lead to boredom of the players with a consequent under-utilization of machines and increase in player dissatisfaction.

It is an object of the present invention to address or at least ameliorate some of the above disadvantages.

BRIEF DESCRIPTION OF THE DRAWINGS

Embodiments of the present invention will now be described with reference to the accompanying drawings wherein:

FIG. 1 is a perspective view of a gaming machine of the present invention showing two game arrangements displayed on a single display screen of the gaming machine,

FIGS. 2 to 6 are representations of the two game arrangements of FIG. 1 at various stages of play on the gaming machine,

FIG. 7 is a schematic representation of the main electronic components of the gaming machine of FIG. 1.

DETAILED DESCRIPTION

With reference to FIG. 1, a gaming machine 10 is provided with a primary display 12. Primary display 12 is an electronic display unit, such as for example a cathode ray tube, plasma screen, liquid crystal display, or any other electronic medium which is capable of displaying video imagery.

In the present invention, display 12 shows at least two video games 14 and 16 side by side, each of which comprises an array of simulated reels 18 and 19 respectively. Reels 18 and 19 are each divided into a number of symbol containing elements 20, of which a subset is visible in the respective displayed portions of the reels 18 and 19 at any one time.

Thus preferably, in this instance as shown in FIGS. 2 to 6, each of the two side by side games 14 and 16, are displayed as a matrix in which the visible portions of the reels 18 and 19 form the columns, and the symbol containing elements, when aligned, form the rows 22 and 23 respectively. Preferably, as can be seen in FIGS. 2 to 6, the matrices comprising both the first game 14 and the second game 16 are of equal size, horizontally aligned and separated one from the other by a gap 15. Preferably, each of the two games includes five simulated reels 18 of which three symbol containing elements 20 of each reel are displayed when the reels are at rest, thus forming two side by side matrices of five columns and three rows.

Both the first game 14 and the second game 16 are associated with a predetermined pay line 24 and 25 respectively, as shown in FIGS. 2 and 3, to indicate possible winning outcomes of the patterns of symbols coincident with these pay lines. Each pay line may be a fixed pay line under the rules of the game, or in at least one preferred embodiment, the pay line for both or at least one of the two games may be a matter of choice for selection by a player.

The symbols populating each set of reels of the first game and those of the second game may comprise two substantially distinct sets of symbols. In at least one preferred form of the invention however, at least some of the symbols are common to both the first game and the second game. In either case, the symbols of each set of symbols include at least one scatter symbol 26 which may determine the conferring of a bonus feature as explained in more detail below. The scatter symbol 26 most preferably is common to both the first game and the second game.

Play of a Game Sequence

It is a feature of the present invention that the two side by side games 14 and 16 are always both played during any game sequence of a wager played on the gaming machine 10. A winning outcome of a game sequence may be determined by a predefined pattern of symbols appearing coincident with a pay line of one or both of the games as shown in FIG. 3.

In one preferred form, spinning of the simulated reels 18 of both the first game 14 and the reels 19 of the second game 16 is initiated at the same instance and the reels brought to rest substantially at the same time also. Reels of each game may all be brought to rest simultaneously or sequentially as illustrated in FIG. 4.

In another preferred form, spinning of the reels 19 of the second game 16 is initiated after initiation of spinning of the reels 18 first game 14. In one instance, the initiation of the spinning of the second game reels 19 commences prior to the reels 18 of the first game 14 coming to rest, but in at least one other possible variation, the reels 18 of the first game 14 have been brought to rest before the spinning of the second game reels is initiated.

In this latter arrangement, the player's anticipation of receiving a benefit may be heightened in that, being aware of some potentially favourable outcome from the pattern of symbols already displayed in the first game 14 matrix, the player eagerly awaits the results of the second game 16.

It is another feature of the present invention, that the conferring of a bonus feature on a player of the game is a function of a distribution of scatter symbols 26 distributed over both games 14 and 16 when the reels of both games have been brought to rest. Thus preferably a minimum of one scatter symbol 26 must appear at some location in each of the matrices displayed as the outcomes of games 14 and 16. More preferably, a minimum of three scatter symbols distributed between the two games will trigger the bonus feature.

When such a distribution of scatter figures occurs at the end of a game sequence, a banner 28 is displayed to indicate that the bonus feature has been won. Banner 28 is displayed as covering at least a portion of each of the displays of games 14 and 16 and across the gap 15 between them.

A triggering of the bonus feature may provided the player with a number of free games, playable on both sets of reels of the first and second games as indicated in FIG. 6.

Game Implementation

Any of the above described embodiments may be implemented on any gaming machine or group of gaming machine provided with a control module. As shown in FIG. 7, a control module 60 is provided with a microprocessor 62 and working random access memory (RAM) 64. The program code driving any of the described embodiments may be introduced into the control module 60 by connection of a data storage device 66. The device may take any of a number of forms, such as read only memory (ROM), erasable read only memory (EPROM), Compact Flash Card, PCMCIA card and the like. Alternatively, control module 60 may incorporate a hard disc drive to which the code may be written via a suitable input device.

Control module 60 acts to implement appropriate elements of the program code according to inputs from a user keyboard 68 and outputs video imagery to at least a main display module 70.
